In this work the influence of sodium selenate on selenium distribution in the chicory (Cichorium intybus L.) cultivars ćAnivipć and ćMonivipć was studied in an aeroponic system in a greenhouse. The plants rootswere moistened every fifteen minutes with a Resh nutrient solution with added selenium (10 mg L-1) in the form of sodium selenate. The content of total selenium in chicory roots and leaves was studied after different periodsof time and different temperatures of exposure to the selenium enrichednutrient solution. In two separate experiments chicory was treated with selenium enriched nutrient solution for 40 days at 10 ^(o)C in the slow growing phase, and for 5, 7 and 10 days at 20 ^(o)C in the developmental phaseat the beginning of formation of the flower stem. The concentration in leaves increased with time during plant growth, and in Se treated groups was 370 and 139 mg kg-1 in ćAnivipć and 460 and 205 mg kg-1 in ćMonivipć leaves after 40 and 10 days of exposure, respectively. A smaller increase in seleniumcontent was obtained in roots, namely to 73 and 46 mg kg-1 in ćAnivipćroots and to 87 and 46 mg kg-1 in ćMonivipć roots after 40 and 10 daysof exposure, respectively. All results are expressed on a lyophilised matter basis. In long and short term treatment, the selenium content in ćMonivipć cultivar was higher than in ćAnivipć. No visible toxic effects on the chicory plants were observedTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
